(5.64 ±0.09 mg/l) and lowest in station B (4.23 ±0.06 mg/l).There was significant difference among the stations
during the study period (Table 3).
The Biochemical Oxygen Demand was similar in stations B, C and D except in station A which recorded highest
oxygen demand in the month of November, 2015 and the BOD dropped in December and became uniform
throughout the study period (Figure 12). The highest value of Biochemical Oxygen Demand was recorded in
station B (0.91 ± 0.08 mg/l) and the lowest value was recorded in station A (0.63 ± 0.04 mg/l). There was
significant difference (P < 0.05) in Biochemical Oxygen Demand among the stations (Table 3).

Alkalinity was low and almost low in stations A and D and was high in station B and C throughout the study
period (Figure 13). Highest value of alkalinity was recorded in station B (180.40 ± 1.40 mg/l) and lowest in
station A (59.10 ±1.16 mg/l) there was significant` difference (P < 0.05) among the stations during the study
period (Table 3).
